GB162-80

Condensing Gas Boiler

1 of 6

Engineering Speciﬁcations

There shall be provided and installed a quantity of _____ Buderus

GB162/80 wall-hung condensing hot water boiler(s), suitable for induced

draft ﬁring with natural gas or propane. Boiler(s) shall have an AFUE

efﬁciency rating of 93.8%.

Boiler(s) shall utilize ALUplus heat exchanger with high quality condensing

heating surface with plasma polymerization for a longer service life and

lower maintenance.

Boiler(s) shall be constructed, tested and labeled in accordance with

ASME Section IV and shall bear the ASME stamp. Boilers shall be CSA

approved and have an applicable Canadian Registration number.

Heat exchanger shall be labeled for 58psig maximum working pressure

rating. An integrated pressure sensor shall ensure minimum and maximum

water pressures are not exceeded.

Boiler shall be capable of modulating ﬁring from 100% to 25% of capacity

continuously based upon (i) supply and return water temperatures, and/or

(ii) outdoor reset computerized control. Gross stack temperatures at full

ﬁring rate shall not exceed 180°F.

Standard equipment shall include a pump group assembly; Grundfos

UP26-99 circulator, integral ﬂow check, supply and return shut-off

valves, pressure gauge, 30psig relief valve and gas supply shut-

off valve. Hydraulic separator option is required for system piping

connection.

Minimal clearances shall be integral to the boiler cabinet design;

a hinged door with locking feature shall be used to access heat

exchanger, burner components, gas valve and sensors.

Integrated controller shall monitor and control all combustion process

functions, control of the boiler water temperature to a value required

by the connected components and shall display current water

temperatures or fault conditions with changes in operation status.

Additional control functions shall include an on/off button, rotary

temperature knobs, LED for burner operation and button for fault

condition reset.

Independent outdoor temperature reset may be accomplished with the

optional AM10 controller; a mounting enclosure shall be included with

the provided resistance dependent sensor.
